Question

A force of 500 dynes is applied
on an area of 20 cm2. Calculate the pressure exerted,

Answer 1

Answer:

pressure =force/area

Explanation:

given ,

force=500dynes

=500×10^(-5) Newtons

area=20cm

=20×10^(-2) metres

Therefore,

pressure = force / area

= [500×10^(-5)] / [20×10^(-2)]

=25×10^(-3)

=0.025 N/ m^2

Answer 2

Given:-

• Force Applied= 500Dynes=500x10^-5N.
• Area=20cm²=20x10^-2m².

To Find:-

• Pressure exerted.

Solution:-

We Know that

$pressure \: exerted = \frac{force \: applied}{area}$

So,

$= > p = \frac{500 \times {10}^{ - 5} N }{20 \times {10}^{ - 2} {m}^{2} }$

$= > p = \frac{50\times {10}^{ 2} N }{2 \times {10}^{ 5} {m}^{2} }$

$= > p = \frac{25\times {10}^{ 2} N }{ {10}^{ 5} {m}^{2} }$

$= > p = \frac{25N }{ {10}^{ 3} {m}^{2} }$

$\therefore p = 0.0025N {m}^{ - 2}$
